A device for the production of raw foil which prevents turbulence

Abstract

This invention provides a foil production apparatus to prevent turbulence, comprising an anode tank and a cathode roller. The cathode roller is disposed within the anode tank, creating a gap between the anode tank and the cathode roller. An outlet is provided at the bottom of the anode tank to allow electrolyte entering from both sides to flow out through the outlet. The distance between the outlet opening within the anode tank and the cathode roller is greater than the distance between the cathode roller and the opening of the anode tank, ensuring that the wave height when the electrolyte entering from both sides converges at the outlet is less than the distance between the cathode roller and the outlet. The electrolyte enters from the upper part of the gap and flows towards the outlet at the bottom of the anode tank. The electrolyte flows only along the gap without collision, resulting in a smooth flow without turbulence. This ensures stable electrolyte concentration during the flow process.

Description

Technical Field

[0001] This invention relates to the technical field of copper foil processing equipment, and more specifically, to a green foil production apparatus that prevents turbulence. Background Technology

[0002] A copper foil production machine is used to produce copper foil. It includes an anode tank and a cathode roller disposed within the anode tank. Electricity flows between the anode tank and the cathode roller. When a copper sulfate solution passes between the anode tank and the cathode roller, copper ions form copper foil on the cathode roller. Generally, the copper sulfate solution enters the cathode tank from the bottom. It is then diverted and flows out from both ends of the cathode tank. Because oxygen and sulfuric acid are generated during electrolysis, acid mist forms at the opening of the anode tank. A high-powered fan is needed to extract the acid mist. To address this, existing technology has designed a top-inlet structure. That is, the copper sulfate solution enters the anode tank from the top and flows out through the outlet at the bottom of the anode tank. This allows oxygen and sulfuric acid to flow out with the copper sulfate solution through the outlet at the bottom of the anode tank, avoiding the generation of acid mist. However, when the copper sulfate solutions from both sides enter the bottom of the anode tank, they collide with each other, causing turbulence at the bottom of the anode tank. This results in an uneven concentration of copper sulfate solution, leading to uneven thickness of the copper foil. Summary of the Invention

[0006] Furthermore, the area of ​​the cathode roller that is enclosed by the anode groove is the production area; the production area is divided into several sections along the circumference of the cathode roller; the anode groove is provided with an inlet at the upper part of each section of the production area and an outlet at the lower part.

[0007] Furthermore, each of the inlet and outlet ports is equipped with an electrolyte supply system; and each anode tank between the inlet and outlet ports is equipped with an electrode system.

[0008] Furthermore, the anode groove extends to the top of the cathode roller; two sets of liquid inlets and outlets are sequentially arranged on both sides of the anode groove from top to bottom; one outlet on one side of the anode groove is located at the vertical tangent of the inner wall of the anode groove, and the other outlet is located at the bottom of the anode groove.

[0009] Furthermore, each production area has a corresponding set of inlet and outlet ports; the inlet port of the later production area is located below the outlet port of the earlier production area, and a partition strip is provided between them; the gap between the partition strip and the cathode roller is smaller than the gap between the cathode roller and the anode groove; the partition strip is inclined towards the outlet port on the side near the outlet port; the partition strip has a concave arc surface on the side near the inlet port, and the tangent direction of the end of the arc surface points towards the gap between the cathode roller and the anode groove.

[0010] Furthermore, the inlet is provided with a nozzle; the nozzle is flat-mouthed so that the electrolyte sprayed from the nozzle is in a waterfall shape; the nozzle is directly opposite the gap between the anode groove and the cathode roller; the width of the nozzle is the same as the width of the anode groove along the axial direction of the cathode roller; the outlet is elongated and the width of the outlet is the same as the width of the anode groove along the axial direction of the cathode roller.

[0011] Furthermore, the inner wall of the anode groove is provided with a plurality of guide grooves; the plurality of guide grooves are parallel and extend circumferentially along the cathode roller.

[0012] Furthermore, each of the liquid outlets is also equipped with a liquid pump; and each liquid inlet is also equipped with a pressure pump.

[0013] Furthermore, the width of the liquid outlet is greater than the gap between the anode groove and the cathode roller.

[0014] Furthermore, a baffle is provided at the bottom of the anode tank below the cathode roller; a copper foil detection device is provided above the baffle to detect the parameters of the copper foil.

[0015] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0016] The anti-turbulence foil production apparatus of this invention has its outlet located at the bottom of the anode tank. The electrolyte, specifically the copper sulfate solution, can only enter the gap between the anode tank and the cathode roller through the upper part of the gap. After entering the gap from the upper part, the electrolyte flows downwards along the gap and towards the outlet at the bottom of the anode tank. During the electrolyte flow, an electric current is applied between the anode tank and the cathode roller, causing the copper sulfate solution to form a thin copper foil layer on the surface of the cathode roller. Throughout the process, the electrolyte enters from the upper part of the gap and flows downwards along the gap to the outlet, from which it then flows out. During this process, the electrolyte simply flows along the gap without collisions. A stable inflow of electrolyte ensures a stable outflow. Simultaneously, as the electrolyte is continuously consumed, its concentration gradually decreases. Under stable electrolysis conditions, the electrolyte consumption rate is the same at all points, thus ensuring a stable concentration of electrolyte during the flow process. Furthermore, when the two streams of electrolyte on both sides of the gap flow along the gap to the bottom of the anode tank, they merge and collide at the bottom of the anode tank, thus generating waves. Because the distance between the cathode roller and the bottom of the anode tank is greater than the distance between other parts of the two, the generated waves cannot rise upwards and reach the surface of the cathode roller.

[0017] It is evident that the electrolyte flows smoothly throughout the entire process without turbulence. Even when the two electrolyte streams collide at the bottom of the anode tank, turbulence does not come into contact with the cathode tube. This ensures stable contact between the electrolyte and the cathode tube, resulting in a copper foil of stable thickness. Attached Figure Description

[0029] Example:

[0030] like Figures 1-4As shown, this invention provides a copper foil production apparatus to prevent turbulence, comprising an anode tank 1 and a cathode roller 2. The overall structure of the copper foil 9 production apparatus is the same as that of a conventional production apparatus. The cathode roller 2 is disposed within the anode tank 1 and can rotate within the anode tank 1. A gap is formed between the anode tank 1 and the cathode roller 2, which allows the passage of electrolyte 12, i.e., copper sulfate solution. An outlet 3 is provided at the bottom of the anode tank 1 so that the electrolyte 12 entering the anode tank 1 from both sides can flow out through the outlet 3. The distance between the opening of the outlet 3 in the anode tank 1 and the cathode roller 2 is greater than the distance between the cathode roller 2 and the opening of the anode tank 1, so that the wave height when the electrolyte 12 entering the anode tank 1 from both sides converges at the outlet 3 is less than the distance between the cathode roller 2 and the outlet 3. The gap between the bottom of the anode tank 1 and the cathode roller 2 can be set according to long-term test results, as long as it ensures that the electrolyte 12 will not contact the cathode roller 2 after surging at the maximum allowable flow rate of the electrolyte 12.

[0031] The anti-turbulence foil production apparatus of the present invention, because the outlet 3 is located at the bottom of the anode tank 1, allows the electrolyte 12, i.e., the copper sulfate solution, to enter the gap between the anode tank 1 and the cathode roller 2 only through the upper part of the gap. After the electrolyte 12 enters the gap from the upper part, it flows downwards along the gap and towards the outlet 3 at the bottom of the anode tank 1. During the flow of the electrolyte 12, electricity is applied between the anode tank 1 and the cathode roller 2, causing the copper sulfate solution to form a thin copper foil 9 on the surface of the cathode roller 2. Finally, the copper foil 9 is torn off the cathode roller 2 and rolled up to form a complete roll of copper foil 9. Throughout the process, the electrolyte 12 enters from the upper part of the gap and flows downwards along the gap to the outlet 3, from which it then flows out. During this process, the electrolyte 12 simply flows along the gap without collision. A stable inflow of the electrolyte 12 ensures a stable outflow. Simultaneously, as the electrolyte 12 is continuously consumed, its concentration gradually decreases. Under stable electrolysis conditions, the electrolyte 12 consumption rate is the same at all points, thus ensuring a stable concentration of electrolyte 12 during its flow. Furthermore, when the two streams of electrolyte 12 on either side of the gap flow along the gap to the bottom of the anode tank 1, they converge and collide at the bottom of the anode tank 1, generating waves. Because the distance between the cathode roller and the bottom of the anode tank 1 is greater than the distance between other parts of the two, the generated waves cannot rise upwards and reach the surface of the cathode roller 2.

[0032] It is evident that throughout the entire flow of electrolyte 12, the electrolyte 12 flows smoothly without turbulence. Even when the two streams of electrolyte 12 collide at the bottom of the anode tank 1, turbulence does not come into contact with the cathode tube. This ensures stable contact between the electrolyte 12 and the cathode tube, thereby forming a copper foil 9 of stable thickness.

[0033] In this embodiment, the area of ​​the cathode roller 2 surrounded by the anode tank 1 is designated as the production area. The production area is divided into several segments along the circumference of the cathode roller 2. The anode tank 1 has an inlet 13 at the top and an outlet 3 at the bottom of each production segment. This means the electrolyte 12 is supplied in segments, with each segment of the production area receiving electrolyte 12. This ensures that the electrolyte 12 supplied to each segment is fresh and of high concentration, allowing the cathode roller 2 to maintain constant contact with a high-concentration electrolyte 12, thus guaranteeing production efficiency. This avoids the situation where a single supply of electrolyte 12 causes the concentration to gradually decrease, affecting production efficiency. Furthermore, each production segment has a set of inlets 13 and outlets 3, preventing the electrolyte 12 from colliding with each other and effectively avoiding turbulence.

[0034] In this embodiment, each set of inlet 13 and outlet 3 is equipped with an electrolyte 12 supply system. Each anode tank 1 between each set of inlet 13 and outlet 3 is equipped with an electrode system. This allows each section of the production area to be individually supplied with electrolyte 12 and current density. Furthermore, the concentration and flow rate of the electrolyte 12, as well as the current density of the electrolyte 12, can be customized.

[0035] As is well known, the concentration, temperature, and flow rate of the copper sulfate solution all affect the parameters of copper foil product 9. Specifically:

[0036] The effect of copper sulfate concentration on the product is as follows:

[0037] Copper foil thickness: An increase in copper sulfate concentration increases the current density, thereby accelerating the copper deposition rate and resulting in an increase in copper foil thickness. Conversely, a decrease in copper sulfate concentration decreases the current density, resulting in a decrease in copper foil thickness.

[0038] Surface smoothness: Excessive copper sulfate concentration may increase impurities in electrolyte 12, thereby forming particles and bubbles on the surface of copper foil 9, affecting the surface smoothness of copper foil 9.

[0039] Mechanical properties: Variations in copper sulfate concentration affect the grain size and structure of copper foil 9, thus influencing its mechanical properties. Generally, higher copper sulfate concentrations result in copper foil 9 with smaller grain size and higher strength.

[0040] The effect of flow rate on the product is as follows:

[0041] Copper foil 9 thickness and uniformity: Variations in flow rate affect the copper ion transport rate in electrolyte 12, thus influencing the deposition rate and thickness of copper foil 9. Higher flow rates can accelerate the deposition rate of copper foil 9, resulting in a thicker copper foil 9. Conversely, appropriate flow rates can help to uniformly distribute the current density, thereby obtaining copper foil 9 of uniform thickness.

[0042] Surface finish: An appropriate flow rate can help the bubbles in the electrolyte 12 to be expelled quickly, reducing the residue of bubbles on the surface of the copper foil 9, thereby improving the surface finish of the copper foil 9.

[0043] Mechanical properties: Changes in flow rate affect the convection velocity in electrolyte 12, thereby affecting the grain size and structure of copper foil 9, and consequently affecting the mechanical properties of copper foil 9.

[0044] The effects of temperature on the product are as follows:

[0045] Copper foil 9 thickness and uniformity: Temperature variations in copper sulfate affect the conductivity and viscosity of the electrolyte 12, thus influencing the deposition rate and thickness of copper foil 9. Generally, higher temperatures accelerate the deposition rate of copper foil 9, resulting in a thicker copper foil 9. Simultaneously, appropriate temperatures help to uniformly distribute the current density, thereby obtaining copper foil 9 of uniform thickness.

[0046] Surface smoothness: Appropriate copper sulfate temperature helps bubbles in electrolyte 12 to dissipate quickly, reducing bubble residue on the surface of copper foil 9 and thus improving the surface smoothness of copper foil 9. Higher temperatures can increase the diffusion and dissolution rates of bubbles, which is beneficial for bubble dissipation.

[0047] Mechanical properties: Temperature variations in copper sulfate affect the convection and diffusion rates in electrolyte 12, thereby influencing the grain size and structure of copper foil 9, and consequently, its mechanical properties. Generally, higher temperatures result in copper foil 9 with smaller grain size and higher strength.

[0048] It is evident that for some customized products, special settings are required for the concentration, temperature, flow rate, and current density of the copper sulfate solution. In existing copper foil 9 production devices, the concentration, temperature, flow rate, and current density of the copper sulfate solution are uniform throughout the anode tank 1. However, in this embodiment, the production area is divided into several sections, each capable of executing a set of parameters for the concentration, temperature, flow rate, and current density of the copper sulfate solution. This results in copper foil 9 with different parameters produced in each section. Ultimately, through multi-stage production, copper foil 9 with various parameters is combined to form a customized product. For example, we can divide the production area into three stages: the first stage focuses on controlling the mechanical properties of the copper foil 9, the second stage focuses on controlling its thickness, and the third stage focuses on controlling its surface roughness. The production areas corresponding to these three stages can each use the corresponding production parameters. The copper foil 9 produced through these three stages satisfies the requirements for mechanical properties, stable thickness, and surface roughness.

[0049] In the prior art, the anode groove 1 generally refers to half of the cathode roller 2. In this embodiment, the anode groove 1 extends to the top of the cathode roller 2. Two sets of liquid inlets 13 and liquid outlets 3 are sequentially arranged on both sides of the anode groove 1 from top to bottom. That is, the production area in this embodiment is divided into four sections. One liquid outlet 3 on one side of the anode groove 1 is located at the vertical tangent to the inner wall of the anode groove 1, and the other liquid outlet 3 is located at the bottom of the anode groove 1.

[0050] During use, the electrolyte 12, entering from the top gap, gradually flows downwards along the gap. As the electrolyte 12 flows, its direction continuously changes tangentially to the inner wall of the anode tank 1. When the electrolyte 12 is vertically downwards, it enters through the first outlet 3 and flows vertically downwards through it. Positioning the first outlet 3 allows the electrolyte 12 to flow into the outlet 3 under the combined action of its own flow and gravity. Simultaneously, below the first outlet 3 is the inlet 13 of the second production zone. The electrolyte 12 in the second production zone flows out through the outlet 3 of the anode section. Both sides of the cathode roller 2 have two sets of inlets 13 and outlets 3, with identical inlet and outlet methods.

[0051] In this embodiment, each production zone corresponds to a set of inlets 13 and outlets 3. The inlet 13 of the later production zone is located below the outlet 3 of the earlier production zone, and a partition strip 4 is provided between them. The gap between the partition strip 4 and the cathode roller 2 is smaller than the gap between the cathode roller 2 and the anode groove 1. This makes the gap between the partition strip 4 and the cathode roller 2 very small, making it difficult for the small amount of electrolyte 12 splashed from the outlet 3 to pass through the narrow gap and enter the next production zone. The partition strip 4 is inclined towards the outlet 3 on the side near the outlet 3, thereby guiding the splashed electrolyte 12 to the outlet 3. The partition strip 4 has a concave arc surface on the side near the inlet 13, and the tangent direction of the end of the arc surface points towards the gap between the cathode roller 2 and the anode groove 1. This allows the electrolyte 12 flowing in through the inlet 13 to enter the gap along the tangent direction of the arc surface under the guidance of the arc surface. This avoids excessive scouring of the cathode roller 2 surface by the electrolyte 12, which in turn prevents scouring of the copper foil 9 on the cathode roller 2 surface.

[0052] In this embodiment, the inlet 13 is provided with a nozzle 5. The nozzle 5 is flat-mouthed, so that the electrolyte 12 sprayed from the nozzle 5 is in a waterfall shape. The nozzle 5 is directly opposite the gap between the anode tank 1 and the cathode roller 2. The width of the nozzle 5 is the same as the width of the anode tank 1 along the axial direction of the cathode roller 2. This ensures that the flow rate of electrolyte 12 flowing out along the length of the nozzle 5 is the same, thereby making the concentration more uniform throughout the gap. The outlet 3 is elongated, and the width of the outlet 3 is the same as the width of the anode tank 1 along the axial direction of the cathode roller 2. That is to say, after the electrolyte 12 flows down along the anode tank 1 to the outlet 3, it flows directly out through the outlet 3 without accumulating in the middle at the outlet 3 to form waves.

[0053] Specifically, the nozzle 5 is also equipped with a pressure-reducing chamber 10 and a flow-stabilizing chamber 11; the electrolyte 12 is pumped into the pressure-reducing chamber 10. The pressure-reducing chamber 10 has a large space, allowing the pumped electrolyte 12 to enter a larger space and reducing its flow rate. The flow-stabilizing chamber 11 is located in the partition wall of the pressure-reducing chamber 10, separated from it by a partition plate. The partition plate has an opening at the top and faces the electrolyte 12 inlet of the pressure-reducing chamber 10 at the bottom. This allows the electrolyte 12 to be sprayed towards the partition plate when entering the pressure-reducing chamber 10, thus slowing it down. When there is a large amount of electrolyte 12 in the pressure-reducing chamber 10, it can overflow the opening at the top of the partition plate and enter the flow-stabilizing chamber 11. The lower part of the flow-stabilizing chamber 11 has an opening that connects to the nozzle 5. At the same time, the width of this opening is the same as the width of the nozzle 5, and the height of the opening is the same at all points, allowing the electrolyte 12 in the flow-stabilizing chamber 11 to enter the nozzle 5 stably, thereby allowing the nozzle 5 to inject electrolyte 12 into the gap at a stable and uniform flow rate.

[0054] With the cooperation of the pressure reducing chamber 10 and the flow stabilizing chamber 11 with the nozzle 5, the electrolyte 12 can be injected into the gap at a stable and uniform flow rate at each point of the nozzle 5.

[0055] In this embodiment, the inner wall of the anode tank 1 is provided with a plurality of guide grooves 6. The plurality of guide grooves 6 are parallel and extend along the circumference of the cathode roller 2. This allows the electrolyte 12 to flow downward along the grooves after entering the gap, thereby avoiding collisions caused by the lateral flow of the electrolyte and the generation of waves. In practice, the depth of the guide grooves 6 is relatively shallow, as long as it can guide the electrolyte 12.

[0056] In this embodiment, each outlet 3 is also equipped with a pump. The pump creates a negative pressure, allowing the electrolyte 12 to flow quickly into and out of the outlet 3. This prevents the electrolyte 12 from lingering at the outlet 3 and filling it, thus avoiding contact with the cathode roller 2 surface. The inlet 13 is also equipped with a pressurizing pump. The pressurizing pump also allows the electrolyte 12 to pass quickly through the outlet 3.

[0057] In this embodiment, the width of the outlet 3 is greater than the gap between the anode tank 1 and the cathode roller 2. This allows the electrolyte 12 flowing into the outlet 3 through the gap to pass through quickly, avoiding any stagnation at the outlet 3.

[0058] In this embodiment, a baffle 7 is provided at the bottom of the anode tank 1 below the cathode roller 2. A copper foil 9 parameter detection device 8 is provided above the baffle 7 to detect the parameters of the copper foil 9. The detection device 8 can be used to detect parameters such as the thickness and roughness of the copper foil 9. The baffle 7 can be used to install the detection device 8 and also to block the waves from the liquid outlet 3 below it. This more effectively prevents the waves from surging upwards and reaching the surface of the cathode roller 2. At the same time, the detection device 8 can detect the parameters of the already produced copper foil 9 at this position, and then use the detected parameters to guide the setting of production parameters in the subsequent production area.

[0059] Furthermore, due to the obstruction of the baffle 7, there is no electrolyte 12 above the baffle 7, making this space extremely suitable for placing the detection device 8. The two streams of electrolyte 12 on both sides are at the bottom of the anode tank 1.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
